The billionaire businessman is the new owner of a custom superyacht roughly the length of a football field, at 357 feet, which Mr. Jones got to take out for a cruise in time for the holidays. Dutch yacht builder Oceanco delivered the fuel-efficient ship to its "proud owners" a few days before Christmas, the builder announced.

Mr. Jones, 76—whose net worth is valued at $6.8 billion—reportedly spent $250 million on the impressive yacht, $110 million more than he paid for the NFL team in 1989. Mansion Global could not independently confirm the final price.

Oceanco and naval engineering firm Lateral rolled out a new energy-efficient design concept for the superyacht, named "Bravo Eugenia" after Mr. Jones’s wife, Genie. The ship has a single-tiered engine room, which allows for the ship’s slender design and more room for guest accommodations, according to the builder.
